CONDENSER FOR STEAM MOTOR-CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 699,726, dated May 13,1902.

Application filed March 24, 1900. Serial No. 10,003, (No m d l.)

To all whom it may concern..-

Be it known that I, FREDERICK W. TURNER, of Cambridge, county ofMiddlesex, State of Massachusetts, have invented an Improvement inCondensers for'Steam Motor-Oarriages, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.

This invention has for its object to construct a condenser which isespecially applicable for use on steam-motor carriages.

In accordance with this invention one or more banks of condensing-pipesare arranged in upright position at the front end of thecarriage-body--as, for. instance, where the usual dasher is locatedand apipe leads thereto from the exhaust-pipe of the engine, and a pipe.leads therefrom for the delivery of the water of condensation.Preferably several upright banks of pipes are employed, in which casethe pipes of each bank will be dis posed in difierent planes, so thatthe pipes of each bank will be located opposite the spaces between thepipes of the bank in front of it. Supports are provided for the severalbanks of pipes, which are attached to the carriagebody, and forsimplicity of construction said supports may consist of uprightchanneled bars attached at their lower ends to the carriage-body, whichare adapted to receive in the channels thereof the ends of the banks ofpipes, and said upright channeled bars are secured together, and thebanks of pipes are connected with said bars. The upper ends of thechanneled bars or other end supports are secured together by a plate,which is preferably disposed obliquely to a horizontal plane, therebydirecting the air downward onto the pipes. A shield is located back ofsaid bank or banks of pipes, which protects the rider from the heat ofsaid condenser, and said shield is formed or provided with an opening ator near its base, which is provided with a removable cover, whereby theopening may be opened and closed at will, and when opened the heat canpass therethrough toward the feet of the rider. The pipe leading fromthe conclensing pipes may lead to a suitable receiver, which is providedwith a drip-cock, and a pump may be provided for returning when saiddrip-cock is closed.

Figure 1 shows in sideelevation a steammotor carriage having a condenserembodying this invention. Fig. 2 is a front elevation of the carriageshown in Fig. 1. Fig. 3 is a plan View of the condenser, theobliquelydisposed top plate being removed. Fig. 4: is a vertical sectionof a portion of the condenser, taken on the dotted line 4, Fig. 2. Fig.5 is a detail sectional view of the shield, showing the opening thereinand the door closing it.

The condenser forming the subject-matter of this invention may beapplied to any ordinary type of steam motor-carriage, one type, however,being herein shown for the sake of illustrating the invention, and inthe type shown or represents the carriage-body, supported upon anysuitable running-gear 5 b, the boiler; c, the engine, andc' theexhaust-pipe leading therefrom. The exhaust-pipe c is connected with apipe (1, leadingto the condenser, and to the upper end of said pipe d acasting d is secured, which projects forward and has as many outlets asmaybe desired, three being herein shown.

e f g represent three banks of pipes,although so far as this inventionis concerned I may employ one or any other number of banks of pipes. Thebanks of pipes are made substantially alike, each bank being preferablycomposed of a single pipe bent at predetermined points to form a numberof horizontally-disposed portions, and the upper end of r.

each bank is connected to the casting d by a suitable union-coupling,and the lower end of each bank is similarly connected to a casting 6',which is constructed substantially the same as the casting d. The pipeswill be composed of thin copper tubing. Notwithstanding each bank isherein shown as comprising but a single pipe bent to present a number ofhorizontal portions, yet said bank is herein referred to as a bank ofpipes as Ido not desire to limit my invention to the particularconstruction shown. The banks of pipes cf 9 are set in upright positionand are located at the front end of the carriage-body at the pointusually occupied by the dasher, and the horizontally-disposed portionsof each bank are located in different planes, so that the horizontalportions of each bank will occupy a position opposite the spaces betweenthe horizontal portions of the bank in front of it. A largecondensingsurface is thus exposed to the direct action of the air. Thebanks of pipesthus provided and connected with the castings d and e aresupported in vertical position by suitable end supports attached to thecarriage-body. Herein such end supports are made as channeled bars h M,there being one bar for each end of each bank of pipes, and saidchanneled bars are secured to the carriage-body in upright position andreceive in the channels thereof the ends of the banks of pipes. As apreferable way of attaching said channeled bars to the carriage-body Ihave herein cut away portions of the lower end of each bar, so as toleavea single fiat .piece, as 2, and said fiat pieces2 are bolted orotherwise secured to the carriage-body. The channeled bars h 1 j at eachend of the banks of pipes are also secured together, and as a preferableway of accomplishing this result I have connected the bars h andj to thebar 'i,which is located between them,by screws 3, which pass between thehorizontal portions of the banks of pipes, and said screws may havemounted upon them suitable sleeves, if desired, although said sleevesare not necessary, so that said screws not only serve to secure theupright bars together, but also serve to connect the banks of pipes tosaid bars. Pins 5 pass through the middle bar between the horizontalportions of the bank of pipesf to assist in accomplishing the sameresult. However, I desire it to be understood thatin lieu of endsupports of this construction and also in lieu of connecting the banksof pipes to the end supports inthis manner other forms of end supportsmay be provided and the banks of pipes otherwise connected thereto.

To the upper ends of the end supports h i j'a plate It is secured, whichis disposed obliquely to a horizontal plane, as shown, and said platenot only serves to hold the end supports in upright position, but alsohas a tendency to direct the air downward. The plate 7t .is'formed orprovided at each end with a downwardly-projecting ear out out of theplate, through which'bolts pass to secure said plate to the upper endsof the channeled bars, and the holes thus formed provide handles to theends of said plate to be grasped by the rider.

The casting e at the lower end of each bank of pipes is connected by apipe e with a receiver e to which a drip-cock e is attached, which maybe opened whenever desired.

A pump e of any suitable description, is provided, which is adapted toreturn the Wa ter of condensation from said receiver 6 to thewater-tank, if desired.

An upright shield m is located back of the condensing-pipes, which maybe constructed riage, and said shield 'm being thus located back of thecondensing-pipes protects the rider from the heat of said pipes; yetsaid shield is provided at or near the bottom-with an opening we, havinga removable cover 712*, so that Whenever desired the heat may be allowedto pass through said opening. At certain times this may be desirable.

It will be seen that by disposing the condensing-pipes at the front endof the carriage body they will be exposed to the direction of the air,and by constructing and arranging them as herein shown a largecondensing-surface is provided. It will also be seen that as thethrottle -valve of the engine is opened wider and more exhaust-steamthus delivered to the condenser the carriage travels faster and thecondensing-pipes will in consequence come in direct contact with moreair to augment their efficiency.
